125x 35 8 简便运算

125x(35+8)=125x43=125x(40+3)=125x40+125x3=5000+375=5375

125x(35+8) =125x(5x7+8) =125x(5x8-5+8) =125x(6x8-5) =125x8x6-125x5 =1000x6-625 =6000-625 =5375

原式=125x43=125x(40+3)=125x40+125x3=125x8x5+375=1000x5+375=5000+375=5375

简便计算过程方法如下解:125*(35+8)=125*43=125*(40+3)=125*40+3*125=5000+375=5375

125x(8+35)=125x8+125x35=1000+4375=5375

原式=125x43=125x40+125x3=125x8x5+375=1000x5+375=5000+375=5375供参考.

125x(35+8)=125x(40+3)=125x40+125x3=5000+375=5375

125*(35+8) =(100+25)(35+8)=35*100+8*100+25*35+25*8=3500+800+875+200=3500+875+800+200=4375+1000=5375

简便运算125X25X32=(125*8)X(25*4)=1000X100=100000

125*(35+8)=125*35+125*8=125*35+1000=125*(4*8+3)+1000=125*4*8+125*3+1000=4000+375+1000=5375
